IMPROVEM ENT IN PLOWS.

Specification forming part of Letters Patent No. 58,91 1, dated October1863.

To all whom it may concern:

Be it known that I, CARLISLE ST. JOHN, of Keosauqua, in the county ofVan Buren and State of Iowa, have invented a new and Improved Plow and Ido hereby declare that the following is a full, clear, and exactdescription thereof, reference being bad to the accompanying drawings,forming part of this specification.

The nature of my invention consists in constructing the land-side andcolter of a plow both of the same piece, in such a form that a goodcolter is made and also the laud-side of a plow. My improved cutter'andland-side is so constructed that when it is not desired to use thecolter it may be reversed or changed end for end, which will then fitand conform to the mold-board, so it may be reversed from rear to frontand front to rear, as may be desired.

1t furtherconsists in attachingabrace which extends from the back orrear end of the clevis under the beam and connected to the standard by ascrew-nut.

It also consists in a novel and peculiar way of attaching the rear endof the beam to the handle, in combination with the brace-rod underneaththe beam.

The advantages of my improvements will at once be seen from the factthat the colter is always attached to the plow, and therefore is notmislaid and lost, which is often the case when colters are detached andattached by means of gripes, keys, and other devices, some of which arevery liable to be misplaced and lost.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

Figure 1 is a perspective view of my improved plow, showing theland-side or cutterplate properly attached. Fig. 2 is a view of themold-board, also showing the cutter. Fig. 3isa plan view, showing themanner of attaching the cutter-plate. Fig. 4 is a side elevation of thecutter-plate. Fig. 5 is a side elevation, showing the cutter-platereversed. Fig. 6 is a top plan view of the standard-plate, showing themanner by which it is secured to the beam.

Figs. 7 and 8 are plan views of corresponding corrugated castingsregulating the guide of the plow. Fig. 9 is a plan view of one of thecorrugated castings, showing the manner by which it is attached to thebeam.

Letters of like name and kind refer to like parts in each of thefigures.

A in Fig.1 represents the cutter-plate of my improved plow. The saidplate may be made of steel or other suitable metal, and in the form, ornearly as may be, as seen in the figures.

The said plate A is secured to the standard B by means of screw-bolts atF F F F, Figs. 1 and 4.

B is the standard rigidly secured to the basepiece 0, and extends up, onthe top of which is the cap piece or plate O,which is also firmlysecured to the standard 13. In the cap or plate 0 are slots provided forthe purpose of admittingthe screw-bolts bywhich itis secured to thebeam, also so that the beam may be adjusted so as to accommodate itselfproperly in the direction of the line of draft.

M is the mold'board, made of steel or iron in the ordinary manner, andsecured by any of the well-known means to the base 0, and mold-board M.

S is the beam, at the rear end of which is secured the corrugated plateG. The said plate G is also provided with slots, through whichscrew-bolts pass. These slots are also for the purpose of adjusting therear end of the beam, so as to accommodate it to the line of draft. Thisplate Gis made to fit in a corresponding corrugated plate, G, which isfirmly fastened to the handle Y.

E is a bracerod running from the rear end of the device under the beamback to near the standard B, where it is inclined and passes through thestandard 13, and secured thereto by means of a screw-nut, a.

l) is the device of ordinary construction.

The operation consists simply by removing the bolts F, which releasesthe land-side or colter from the standard, and it may be reversed andsecured by means of the same bolts, F, so that the cutter may beattached or do tached conveniently.

Having thus described my invention, what i beingprovided with a strapand socket, in I Claim as new, and desire to secure by Letcombinationwith the bean) S and biaee'rod ters Patent,is I), for the purposes andsubstantially as de- 1.
